my book shows me 3 graphs. One is Imperialism in Africa, c. 1900 that shows by 1900, European imperialist nations controlled vast amounts of territory in Africa.
Second is Imperialism in Asia, c. 1900, that shows the U.S. and japan joined European nations in exerting economic control, or "spheres of influence," in Asian nations.
and third Value of United States Exports, 1870-1920 that shows the expansion of American businesss into international markets in the late 1800s and early 1900s let to the rapid rise in U.S. exports during this period.
my question says to use the 3 graphs to explain why the U.S. supported a policy of the Open Door.
pleease help me with this :/
